the pyloric sphincter controls the passage of food(chyme) from the stomach into the small intestine. The movement of food (chyme) through the small intestine and large intestine is controlled by paralysis. The iliocecal valve is a sphincter muscle that is normally contracted to prevent the contents of the colon from moving back into the ileum (last portion of the small intestine). The anal sphincter controls the movement food (feces) from the rectum to outside the body.
